In his magnum opus more than 25 years in the making, psychologist, eco-therapist, and wilderness guide Plotkin (Soulcraft ) brings forth a new model for the whole of human life and spirituality in our world in dire ecological need, spoiled by “patho-adolescent society.” Beginning fittingly with elder eco-sage Thomas Berry, Plotkin calls us to a fresh circular conception of individual and collective evolutionary life genuinely reconnected to the wild of nature. Using the indigenous template of the four compass directions, his eight stages on the wheel of spiritual development are the Innocent, Explorer, Thespian, Wanderer, Soul Apprentice, Artisan, Master and Sage. “The Wheel is a deep-structure portrait of nature-and-soul-oriented cultures, a portrait that encompasses child-raising practices, core values, stages of growth, rites of passage, community organization, and relationship to the greater Earth community,” he writes. Leaning heavily on psychology, Plotkin also draws upon a heavenly host of the rich sources that inform a lifetime including poetry, global cultures and much more. Graceful prose is counterbalanced with diagrams and clear chapter structure. Plotkin offers an essential, weighty book for our perilous times. (Jan.)
